Versuchsvorschrift

The same procedures as described in Example 10 were carried out by using a mixture of 7.61 g (50 mM) of 4-n-propylcatechol, 15 ml of acetone, 30 mg of p-toluenesulfonic acid monohydrate and 15 ml of benzene. 5 n-Propyl-2,2-dimethyl-1,3-benzodioxol was obtained in the yield of 9.13 g (47 mM) as colorless transparent liquid having a boiling point of 82°-87° C./3 mmHg.
